Telkom once again disappointing customers

Last year I was a client of telkom where I resided previously...in May or so I closed my account and relocated... I went into the Telkom rosebank to close this account. I spent almost 4 hours there before being served...anyway...at the end of it...my account was to apparently be closed later that month..A month later...and then 2mobths later I was still getting a bill. I went back there and waited for service again...and had to now lodge an enquiry because the lady who helped me the first time could not say why I was still getting a bill..I continued to get a monthly bill until August and then had to go in again and lodge another complaint... It was in December someone called me on behalf of telkom and said it was sorted out and asked me to pay an amount to close the account...I was happy and the money was paid...I asked for a paid up letter and to say this account was closed...then 2weeks ago I app**** for a contract...little did I know that Telkom, did not close my account as promised and had actually went on to label me as a defaulter... So I contacted Telkom, a lady by the name of Charmaine Dafel, who sent me an email about her contacting Transunion and it will take 10 days to sort out...the next day I contacted transunion and they denied any such letter/information from Telkom, so I was furious and called Charmaine, and expressed my disappointment and feelings, and went on to say that this was uncalled for and this has impacted my financial status negatively. I also brought it to her attention that not once did Telkom apologize for this inconvenience it has brought me. To my astonishment, her response was that she is not Telkom, she does not give apologies and I should go back to Rosebank Telkom and ask the guys there who did not close my account in the first place, they should apologies to me! I have lost out financially because of this and it is absolutely unfair that Telkom can do such things! I am considering taking this up with the relevant authorities as there is absolutely no accountability!!!
